t ermo conv Algorithm
The termoConv algorithm, also known as the thermocouple conversion algorithm, is a computational method used to convert the voltage readings obtained from thermocouples into accurate temperature measurements. Thermocouples are widely employed temperature sensors, consisting of two dissimilar metals joined together at one end, which generate a voltage proportional to the temperature difference between the junction (hot end) and the other end (reference or cold junction). Since the relationship between the voltage and temperature is non-linear, termoConv algorithm plays a crucial role in the precise determination of temperature by applying the appropriate calibration equations, coefficients, and compensation techniques.
The termoConv algorithm generally involves two important steps: linearization and cold junction compensation. In the linearization step, the algorithm uses polynomial equations or lookup tables to convert the measured thermocouple voltage into temperature. These equations, also known as the NIST (National Institute of Standards and Technology) polynomials, are specific to each type of thermocouple and are derived from experimental data. The coefficients used in these equations are determined using standard reference functions provided by NIST or other international standards organizations. In the cold junction compensation step, the algorithm accounts for the temperature of the reference junction, which is typically measured by a separate temperature sensor like an RTD (Resistance Temperature Detector) or a thermistor. By combining the linearized thermocouple temperature and the reference junction temperature, the termoConv algorithm delivers an accurate temperature reading that can be used in various applications, such as process control, HVAC systems, and scientific research.
